Rockwell hardness tester is selected for hardness test of hardware stamping parts. Small stamping parts with disordered shape can be used to test the small plane, which can not be tested on ordinary Rockwell hardness tester.

Stamping processing includes blanking, zigzag, drawing, forming, finishing and other processes. The processing data of stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal plate and strip data, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tinplate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.

PHP series portable external Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in the field of metal processing and mechanical manufacturing. Stamping parts processing is a processing method of using die to separate or form metal strip. Its application range is very wide.

The main purpose of hardness testing of stamping part data is to confirm whether the annealing degree of purchased metal sheet is suitable for the stamping part processing to be carried out later. Different types of stamping part processing technologies need different hardness grades of sheet metal. The aluminum alloy plate used for stamping can be tested with a Vickers hardness tester. When the thickness of the data is greater than 13mm, the Vickers hardness tester can be used instead. The Vickers hardness tester should be used for pure aluminum plate or low hardness aluminum alloy plate.

In stamping industry, stamping is sometimes called sheet forming, but there are some differences. The so-called sheet forming refers to the forming method of plastic processing with sheet, thin-walled tube, thin profile, etc. as the original data. At this time, the deformation in the direction of thick plate is generally not considered.
